Wrath of the Infinite

With a single word you conjure the pure elemental fury of raw unchallenged power, you channel every drop of magic inside your being into this spell, consuming all spell slots. The area of the storm consists of up to ten 30-foot cubes, which you can arrange as you wish. Each cube must have at least one face adjacent to the face of another cube. Each creature in the area must make a Dexterity saving throw. It takes 4d100 fire damage, 1d100 necrotic damage, 20d10, cold on a failed save, or half as much damage on a successful one. (DC: 30)

This spell bypasses all immunities, resistances magical items, etc.

The fire damages objects in the area and ignites flammable objects that aren't being worn or carried.

NOTE: If a god or divine being is killed by this spell, they CAN resurrect themselves after three days since they died.

If the caster of this spell is influenced by an anti-magic field, they can still cast this spell, shredding the anti-magic barrier to shreds and incurring 130 psychic damage.
